lokhor: Can anyone with the I9100T that has flashed ICS tell me which modem they are using for best performance on Telecom?

I9100TDCKL1 on both GB and ICS, better range than the DOKG2 also and I think Lee can confirm this.

Cheers for that, I just flashed DCKL1 and I noticed an immediate improvement of the signal strength! In my totally unscientific test, I first kept the phone in a fixed spot in my room for around 5 minutes and noticed an average signal reading of -79 dBm on DOKG2. After flashing DCKL1, I now see an average of -76 dBm, with the phone still in the same spot. :)

Confirmed. I'm still running with this modem on ICS (although on Skinny rather than XT - for what it's worth).

networkn: I see ROM LPQ and LQ7, which is later and which is which? Sorry for the noob question.

You mean LPQ and LP7? LP7 is the latest, released shortly after LPQ and with improved scrolling and some other bug fixes. Apparently. I'm on LPQ and it's all good for me. Most custom Samsung-based roms are LPQ because it was the first supposedly official rom.
